What intervention is appropriate for managing supine hypotensive syndrome during pregnancy?

Managing supine hypotensive syndrome, which occurs when a pregnant woman lies flat on her back, involves addressing the pressure the fetus places on the inferior vena cava, leading to reduced venous return to the heart and decreased cardiac output. The most effective intervention is to position the patient on her left side, specifically the left-lateral side position. This position alleviates pressure on the inferior vena cava, allowing for improved blood flow and reducing the symptoms associated with hypotension.

Encouraging the supine position would worsen the condition, while applying heat packs may not have any impact on the underlying issue of vein compression. Increasing fluid intake might be beneficial overall, but it does not directly address the mechanical compression affecting blood return during episodes of supine hypotensive syndrome. Thus, the left-lateral position is the most appropriate, providing immediate relief and promoting better oxygenation and perfusion for both the mother and fetus.
